This molecule is the "gas" in the water-gas shift reaction used to produce hydrogen gas, and it can be produced by the reaction of concentrated sulfuric acid and formic acid. This molecule is reacted with impure nickel in the Mond process, and blast furnaces reduce hematite by reacting it with this molecule. It is produced by insufficient combustion of hydrocarbons, which is why running an automobile in an enclosed area can lead to high air concentrations of it. For 10 points, name this heteronuclear diatomic molecule that has over two hundred times as high a binding affinity for hemoglobin as oxygen does.
